Abstract

The reaction of CpCo(CO)₂ with elemental sulfur yielded the new sulfur-rich compound Cp₄Co₄(μ₃-S) (μ₃-S₂)₃ (1). The structure of 1 contains a Co₄S₇ core composed of three μ₃-disulfido ligands and one μ₃-sulfido ligand. PEt₃ abstracts sulfur from 1 to yield the new compound Cp₄Co₄(μ ₃-S)₃(μ₃-S₂) (2). Compound 2 is also a cage compound, but it contains three μ₃-sulfido ligands and only one μ₃-disulfido ligand. Compound 2 is converted back to 1 by reaction with elemental sulfur. The selenium homologue Cp₄Co ₄(μ₃-Se)₃(μ₃-Se₂) (3) was obtained from the reaction of CpCo(CO)₂ with elemental selenium. The structures of 1, 2 and 3 were determined by single-crystal X-ray diffraction analyses.
